I need to learn something about xv, right now piave uses SDL to display the 
video, which is nice very easy to implement, but slow. I have to use xv, or 
preferrable a configurable target (I thought GStreamer could do that for me, 
it probably can, but I don't (yet) know how.

Anyway, this reminds me of something very important we did not yet talk about 
concerning the communication part. We nned to tansport all kinds of snapshots 
from the effect engine to the GUI. A Track in the timeline should contain a 
very small snapshot of the first and last frame at least, and it would be 
nice to have the first frame of a clip in the file list too. How should we do 
that?
We cannot have tenth of embeded XWindows.
We probably don't want to push the images through a socket.
We could use a pipe in the filesystem or shared memory.
Shared mem is probably much faster but won't work if GUI and effect engine are 
on different systems.


Cheers,
Rolf
